​In ancient China, Lưu Ngưng Chi had the reputation of being a man of principle. He gave his share of his inheritance to his siblings because he wanted to earn his own livelihood without depending on anybody. He even refused to become an official and chose to travel everywhere instead.

​One day, someone came and claimed that the shoes that Lưu was wearing was his. Lưu immediately gave up his shoes without any resistance. Later, the same man found his own shoes and came to apologize and wanted to return Lưu’s shoes. Lưu categorically refused.
